Specifications: Compatible with 30W-50W pyrography machines. High impedance tips are made of high-resistance and high-temperature resistant alloy. At high temperatures, the tips do not bend, oxidize, or produce excessive carbon. The strength at temperatures below 600 degrees ensures no bending occurs without heating, and the bending resistance of the writing head made with electric heating wire performs better than those used at 800 degrees. Includes 23 different tips for various functions such as large-scale rendering, delicate rendering, and drawing uniform lines. Note: Please allow for a 1-2cm error due to manual measurement. Specifications: Diameter: 1mm. Length: 27-32mm. Width: 9-10mm. Power: 30-50W. Temperature: 0-1000°C (for general use). Service voltage: 3-5V. Material: Chrome-nickel alloy (Cr: 23~26, Ni:15~18). Suitable for models: LH30, LH40, LH50, LH60, LH70, LH80, LH90, LH100. Note: Please allow minor measurement deviations due to manual measurement. Item color may appear slightly different in photos due to monitor calibration differences. Package Contents: 23pcs Chromium Nickel Alloy Pyrography Machine Wire High Impedance Nib Tips.
